Hi all! This isn't anything like urgent, or ultimately even particularly important, but I find it a curious oddity and thought to in quire if any of you have thoughts on it... On my Centos 6.5 box, I have a PATA CDRW drive, and a SATA dvd drive. when playing a CD in the CDRW drive, every short while I get a sudden break in the audio while the CD is spun up. when playing the same CD in the dvd drive, I get no such phenomenon. I'm theorizing that it's one of: 1. weird PATA drive (next time I open up the case I'll try one of the spare drives I have on the shelf, and see). 2. some issue with the way PATA drives work 3. some issue with the way Linux accesses PATA drives. 4. something else. I note that the drive spins madly once it starts up to read a block of audio data, slowly spinning down afterwards. If the next read of audio data occurs before it has stopped, it will read it and spin up further. if, however, it has spun down (I assume stopped) until the drive seems to be stopped (or at least silent) I get the pause. Is there some knob to twist in the PATA subsystem that would have some effect on this? or any other pertinent thoughts. -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------
